.ram files aren't audio files, if you open them in a text editor you will see an URL using the rtsp or mms protocol that is pointing to a real realmedia file (.rm or .ra) but you can't direclty save them to your hard disk. For that you'll need a program that will connect to the rtsp/mms server and will save the file while it is being played, you won't hear it though (or see it if it's a video), I mean the download rate will be as fast as the file would normally play. So to get one of these .rm or .ra files, open the .ram file in a text editor, copy the URL and paste it in
StreamboxVCR. StreamboxVCR will connect to the server and save it on your hard disk to the target folder you specified.
